Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F1051CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 1.05 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical. Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must match.

Mechanical Specifications: Package type must be 0805 (2012 Metric) with identical physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Two terminations are required.

Material & Composition: Thick film construction is mandatory for all substitutes.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are required. REACH Unaffected status and EAR99 ECCN classification apply to all qualified substitutes.

All identified substitute parts meet these criteria and are classified as either Direct or Similar equivalents based on feature alignment.
